GPS/GNSS splitters
Designed for small-cell and distributed antenna systems
GPS Source has released of a line of GPS/GNSS splitters created for the small-cell wireless and distributed antenna system markets. Specifically designed for the L-band frequency, they can eliminate the cost of multiple antennas and long cable runs in wireless installations. With four or eight outputs, the new line of splitters make it possible to use a single GPS referencing antenna and cable arrangement for multiple synchronized systems. The splitters include features such as DC bias select and amplification. GPS Source RF signal splitters typically operate in conjunction with an active GPS antenna; consequently, a GPS RF signal splitter must have provisions for managing the DC voltage to the active GPS antenna. The S14GT and S18GT splitters will power an external GPS antenna from any of the RF outputs. A “hunt-and-pick” circuit is used to select only one DC input for power should more than one source be connected. Designed for redundancy, if the selected DC bias input should fail, the DC bias will automatically switch to another DC input to ensure an uninterrupted power supply to the active antenna.

Wideband Antennas
For precision industrial, agricultural and military OEM applications
A new series of L1 band wideband antennas for OEM applications is offered in three formats:
▪ TW2106/TW2108 — GPS L1
▪ TW2406/TW2408 — GPS + GLONASS
▪ TW2706/TW2708 — Galileo, BeiDou, GPS + GLONASS
Each antenna type features Tallysman’s Accutenna technology, which provides high rejection of multipath signals, with low axial ratios and tight phase center variations (PCV). Each is available with a brickwall pre-filter option to protect against saturation by high level subharmonic and L-band signals. The antenna printed circuit boards (PCBs) are 56 millimeters in diameter with four plated holes for secure mounting. They are available with a variety of connectors and custom cable lengths, and can be custom-tuned. All of them are REACH and ROHS compliant.

Survey
Hydrographic rover accessory
Hydrographic Echo Sounder designed for GNSS rover
The SLD-100 GNSS Rover accessory facilitates hydrographic measurement in bodies of water up to 100 meters in depth. it is designed for anyone who finds themselves needing to survey into bodies of water, streams and rivers. With survey-grade accuracy, the SLD-100 can be added to any brand GNSS RTK rover to allow for position and depth measurements to be made simultaneously. With a built-in 10-hour lithium battery and transmitter unit with Bluetooth connectivity, the SLD-100 provides standard-depth data streams in several industry-standard NMEA formats at 1 Hz, 4800 bps, providing compatibility with any hydrographic surveying software package. Position and depth information is externally logged on a computer or controller. Included transom mounting hardware enables easy installation.

Rugged GNSS antenna
Provides protection
in harsh environments
TriAnt is small, thin and rugged high-performance GNSS antenna. It measures 128 x 128 millimeters (mm) square and 39 mm thick. It can be mounted with three screws to flat surfaces. It is designed for applications such as machine control and surround anennas of the TRIUMPH-4X. The antenna cable is routed through the center of the antenna (TNC connector) for protection in harsh environments. The TriAnt can also be mounted on poles (1–14 inches thread) using its mount-pole attachment, which increases the thickness to 54.5 mm.

iOS-ready L1 receiver
Turns iPad or iphone
into mobile mapper
The X20i L1 GPS receiver by CHC Navigation is powered by a high-precision L1 GPS engine. Its integrated Bluetooth chip enables it to wirelessly collect submeter positions in real- time or centimeter post-processed on an iPhone or iPad. All location-aware apps on the iPhone and iPad are compatible with the X20i. Immediately after pairing and answering the security question allowing the X20i to take control of location services on the iOS device, 1 million iOS applications are capable of utilizing the high-accuracy data of the X20i, and become accurate to either 1 foot or 1 centimeter. Apps that can make use of the high accuracy include TerraGo Edge, ESRI’s ArcView Connector and those by CarteGraph Systems.

Sub-meter precision
for android devices
BlueStarGPS offers both GPS and GNSS options in a rugged, lightweight package. The BlueStarGPS device was designed to meet sub-meter mapping and data-collection needs in the pipeline and utility industries. It provides sub-meter precision without post-processing, and maintains accurate positioning when the SBAS signal is obstructed. This means it can function under trees, around buildings and in rugged terrain where other receivers can fail. The BlueStarGPS is designed specifically for use with Android mobile devices, such as smartphones, tablets or notebook computers, as well as cable and pipe “locating” tools with a connectivity range
of up to 1 kilometer.

Smart module
Module harnesses
the power of machine learning
The NVIDIA Jetson TX1 module is designed to power smart devices — including drones that don’t just fly by remote control, but navigate their way through a forest for search and rescue. It is an embedded computer designed to learn to recognize objects or interpret information, incorporating capabilities such as machine learning, computer vision and navigation into a single system. This technology expands the ability of machines to operate on their own and adapt to their surroundings by recognizing images, processing conversational speech, or analyzing a room full of furniture and finding a path to navigate across it.
